January 12, 1860
To the Senate of the United States:
In compliance with the resolution of the Senate in executive session of the 10th instant, I transmit herewith the report of the Secretary of State and the papers accompanying it, relating to the treaties lately negotiated by Mr. McLane and to the condition of the existing Government of Mexico.
It will be observed from the report that these papers are originals, and that it is indispensable they should be restored to the files of the Department when the subject to which they relate shall have been disposed of.
JAMES BUCHANAN.
